I have edited a number of posts here. I found that whenever reputation decreased by two, it was accounted for, for I checked and found that a post which I edited was deleted.
However, a number of times I have seen it go up by 2. Recently (this month), I found my reputation go up from 201 to 203, but nothing in my profile/recent reputation changes accounted for it. If it were, then there should have been a +2 recorded in my reputation history!
Why does this happen?
